Vivipary occurs when two conditions are met; the development of high humidity between the shell and shuck and high temperatures during ripening. The incidence of vivipary varies with crop load, irrigation, tree crowding, soil depth, and length of the growing season.
Description
When green shucks fail to open and the kernel develops, there is often an increase in the number of nuts which germinate and sprout on the tree. The longer the fruit remains on the tree, the greater the degree of vivipary. Pecan trees growing in southern Oklahoma will be more susceptible to vivipary than those in northern Oklahoma.
